Slave Doll

When my grandmother died she passed on to me a doll supposedly made in limited quantites by a woman (perhaps in the Chicago area) who then broke the mold.

The doll is named Caledonia and is based on a former slave that the maker knew about in some capacity. I believe there was a husband and perhaps some children made as well.

The head, hands and feet/lower legs are made of hard material (bisque? composite?) and hand-painted; the body is cloth. The clothes were hand-made as well.

My grandmother told me the gray hair on the doll's head was real human hair and I have another small sample in an envelope that was provided by the maker of the doll.

There are no identifying marks, labels or anything else to figure out who made the doll or how old it might be. I am including four pictures and would love any information about this doll.
